Yes, bet on a Man U win. Fergie will find the best way to stop Lionel Messi. Barca keep possession like no other team in the history of the game. The key idea for Man U is to pile the pressure on their defenders and not allow them to bring the ball out of the back to their playmakers. Man U will play with great intensity. Sheer energy is Manchester United's greatest strength when they are playing well. Several of their players could run all day and keeping their passing at a consistently high tempo allows them to overwhelm opponents at times. It is no co-incidence they complete so many second-half comebacks, with many teams who score against them eventually deciding to sit back, inviting wave after wave of attacks. Fergie may leave out slow & old players like Giggs, Rio & Carrick. Smalling takes over from Rio in defense which also has fast players like Rafael, Evra, Vidic. They may need Fabio to mark Messi all over the field. Park to run all over midfield to win balls. And there is Valencia and Nani to provide width & feed the final ball to Rooney & Chico. And of course, Edwin in goal is a superb custodian.
